+1. Not all tone control circuits are born equal, implementation is everything. In a well designed amp I would challenge anyone to tell the difference blind - Its astonishing how huge differences suddenly disappear. I have tried it myself with cables, dacs & tone controls and could detect exactly zero difference... Anyone that claims they can hear the difference yet have never put it to the test really ought to.
